Why Multi-Agent Systems Break at the Seams: Designing Reliable Handoffs
There's a pattern that plays out repeatedly when teams graduate from single-agent to multi-agent AI systems: individual agents work beautifully in isolation, but the system as a whole behaves unpredictably. The agents aren't the problem. The boundaries between them are.
Studies across production multi-agent deployments report failure rates ranging from 41% to 86.7% without formal orchestration. The most common post-mortem finding isn't "the LLM gave a bad answer" — it's "the wrong context reached the wrong agent at the wrong time." The seams between agents are where systems quietly fall apart.
